Kishu Binchotan Charcoal Towel
Charcoal that works through the fiber, not on top of it
Most towels that claim deodorizing properties use a surface coating — a finish applied after weaving that washes away over time. The Kishu Binchotan works differently. Fine charcoal powder from Kishu Ubame Oak is kneaded into the cotton and rayon yarn before the towel is woven. It is part of the fiber. The grey and black colorways are not a dye — they are the charcoal expressing itself through the material.
Charcoal fiber — how it works
Two of the three towels in this range contain charcoal fiber. Fine charcoal powder is kneaded directly into the cotton and rayon yarn before weaving — not applied as a coating or surface treatment. The charcoal becomes part of the fiber itself.
Charcoal has a highly porous surface structure. These microscopic pores physically trap odor molecules — absorbing them rather than masking them. When the towel is washed and dried, the absorbed molecules are released and the effect resets. It works through repeated use, for the life of the towel.
The charcoal content naturally turns the yarn grey or black. The coloring is the material expressing itself — not a dye. It will not fade with washing.
Gauze and pile — why it works
Most bath towels are a single construction: terry pile on both sides, built for bulk. Uchino's approach is different. Their towels use Zero Twist yarn — a patented construction where the fiber is not twisted before weaving. This creates longer, softer loops that absorb moisture on contact and resist the flattening that happens with standard twisted yarn over time.
The gauze and pile double-face construction takes this further. Gauze on one face, pile on the other. The gauze side is lightweight and fast-drying. The pile side is soft and absorbent. Together they produce a towel that is significantly lighter than European terry, dries between uses, and does not need to be heavy to perform.
